 a second colored hard coating layer disposed at another surface of the plastic substrate.   
     
     
         3 . The window panel of  claim 2 , wherein
 at least one of the first colored hard coating layer and the second colored hard coating layer includes a blue pigment.   
     
     
         4 . The window panel of  claim 3 , wherein
 the blue pigment includes a metal phthalocyanine complex, wherein the phthalocyanine is optionally substituted with one or more halogens.   
     
     
         5 . The window panel of  claim 4 , wherein
 the polymer solution to form at least of one of the first colored hard coating layer and the second colored hard coating layer includes the metal phthalocyanine complex at about 10%, wherein the phthalocyanine is optionally substituted with one or more halogens.   
     
     
         6 . The window panel of  claim 4 , wherein
 the polymer solution to form at least of one of the first colored hard coating layer and the second colored hard coating layer includes the metal phthalocyanine complex at about 5%, wherein the phthalocyanine is optionally substituted with one or more halogens.   
     
     
         7 . The window panel of  claim 2 , wherein
 at least of one of the first colored hard coating layer and the second colored hard coating layer is formed with a thickness of 20 μm.   
     
     
         8 . The window panel of  claim 2 , wherein
 a yellow index is less than 1 by the first colored hard coating layer and the second colored hard coating layer.   
     
     
         9 . A display device comprising:
 a display module including a plurality of display elements; and   a first window panel disposed at one surface of the display module,   wherein the first window panel includes
 a plastic substrate formed of a transparent polyimide, and 
 a first colored hard coating layer disposed at one surface of the plastic substrate. 
   
     
     
         10 . The display device of  claim 9 , wherein
 the first window panel further includes   a second colored hard coating layer disposed at the other surface of the plastic substrate.   
     
     
         11 . The display device of  claim 10 , wherein
 at least one of the first colored hard coating layer and the second colored hard coating layer includes a blue pigment.   
     
     
         12 . The display device of  claim 11 , wherein
 the blue pigment includes a metal phthalocyanine complex, wherein the phthalocyanine is optionally substituted with one or more halogens.   
     
     
         13 . The display device of  claim 12 , wherein
 the polymer solution to form at least of one of the first colored hard coating layer and the second colored hard coating layer includes the a metal phthalocyanine complex at about 10%, wherein the phthalocyanine is optionally substituted with one or more halogens.   
     
     
         14 . The display device of  claim 12 , wherein
 the polymer solution to form at least of one of the first colored hard coating layer and the second colored hard coating layer includes the a metal phthalocyanine complex at about 5%, wherein the phthalocyanine is optionally substituted with one or more halogens.   
     
     
         15 . The display device of  claim 10 , wherein
 at least of one of the first colored hard coating layer and the second colored hard coating layer is formed with a thickness of 20 μm.   
     
     
         16 . The display device of  claim 10 , further comprising
 a second window panel disposed at the other surface of the display module,   wherein the second window panel is formed the same as the first window panel.   
     
     
         17 . The display device of  claim 9 , further comprising
 a second window panel disposed at the other surface of the display module,   wherein the second window panel is formed the same as the first window panel.   
     
     
         18 . The display device of  claim 17 , wherein
 the second window panel further includes   a second colored hard coating layer disposed at the other surface of the plastic substrate included in the second window panel.   
     
     
         19 . The display device of  claim 4 , wherein the metal phthalocyanine complex is HELIOGEN blue. 
     
     
         20 . The display device of  claim 12 , wherein the metal phthalocyanine complex is HELIOGEN blue.
